The Twins right-hander, on the disabled list following a bout of back spasms, pitched six innings for Class A Cedar Rapids on Monday night. Pelfrey allowed two hits -- a solo homer to Peoria's Jacob Wilson and a triple -- but walked none and struck out six.

Pelfrey, who also hit a batter, reported after his rehab start that he felt fine.

He remains on track to return to the Twins' rotation on Saturday at Toronto.
